Customize the length, width and thickness of FPC or cable, adjust the pin arrangement according to the interface type, and select the appropriate connector. Make your display or circuit board simple and safe with an excellent FPC solution.
A touch screen can be added according to your requirements, there are three options: resistive touch screen, capacitive touch screen, infrared touch screen. Or add protective glass as needed
Display screens with different optical parameters can be designed according to needs, such as brightness, color gamut, response time, gamma and other parameters, and anti-glare, anti-fingerprint coatings, etc. can also be added
The circuit board we designed can convert the interface of your display into an HDMI interface. If your product does not have any display control capabilities, you can use our serial display and only need to use simple commands to control the displayed content through RS232/458
0.91-inch OLED Display drawings and interfaces
0.91-inch monochrome oled display with a resolution of 128×32 that displays white. Driver IC SSD1316, supports I2C serial interface. Active area: 22.38mmx5.58mm. Welded FPC is adopted, and the length of display fpc and interface definition are supported. If you have custom needs, please contact us.
The outline drawing is as follows:
Interfaces are defined as follows：
| Pin | Symbol | Detail |
| 1 | C2P | Data transmission line |
| 2 | C2N | Data transmission line |
| 3 | C1P | Data transmission line |
| 4 | C1N | Data transmission line |
| 5 | VBAT | Power Supply for DC/DC Converter Circuit |
| 6 | VBREF | NC |
| 7 | VSS | This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground |
| 8 | VDD | This is a voltage supply pin. It must be connected to external source |
| 9 | RES | This pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin pull high during normal operation. |
| 10 | SCL | IIC Bus Clock Signal |
| 11 | SDA | I2C Bus Data Signal |
| 12 | IREF | Current Reference for Brightness Adjustment |
| 13 | VCOMH | |
| 14 | VCC | This is the most positive voltage supply pin of the chip. A stabilization capacitor should be connected between this pin and VSS when the converter is used. It must be connected to external source when the converter is not used. |
0.91 -inch 128 x32 OLED application cases
arduino is a very popular development board, which can be used to make many DIY products. The 0.91 inch OLED product has a version suitable for arduino. The OLED display screen is attached with a circuit board, which leads out the circuit and uses pins for customers’ convenience
With the rapid development of consumer electronics, every household has a lot of electronic devices that need to be charged, such as mobile phones, game consoles, power banks and other devices. If all the devices are charged, a lot of plugs are needed. The socket integrated with multiple USB ports can solve this problem, and it is equipped with an OLED display, which can display the charging voltage and current of each way. Convenient for customers to use.
